Moreno, Mackay & Pacheco, 2013
Only known from the type material, nothing is known about the biology of Solenopsis impolita.
Pacheco and Mackay (2013) - Worker - The workers are small and concolorous pale yellow in color. The head is coarsely punctate with an eye of one ommatidium. The lateral clypeal teeth are short, but well developed and the extralateral teeth are absent. The scape is short at 0.240 mm in total length. The sculpture of this ant is smooth and it has little pilosity on body surfaces.
Solenopsis impolita is unique in the pygmaea species complex. It is easily recognized in that the workers have only one ommatidium and are nearly devoid of pilosity. Additionally, it is one of few species that is completely smooth, lacking even horizontal striae on the metapleuron; a trait found in nearly all species.
